Description

The contents of the present invention relate to the structure of a fall prevention device for a fluorescent tube type LED lighting device.

  Mercury or the like is enclosed inside the glass tube of a conventional fluorescent tube. When this fluorescent tube was dropped and damaged, it was impossible to avoid injury due to glass scattering and health damage due to mercury scattering.

  In recent years, fluorescent tube LED devices using LED elements have been developed instead of straight tube fluorescent lamp tubes. Although the glass tube bulb has been changed to plastic and the risk of breakage at the time of dropping has decreased, some fluorescent tube LED devices have increased in weight due to the use of aluminum to enhance the heat dissipation function.

In particular, the fluorescent tube type LED device having a built-in lighting circuit has increased in weight, and the conventional fall prevention device for a straight tube type fluorescent tube has not been sufficiently effective as an anti-seismic measure.

  When replacing a conventional straight tube type fluorescent tube with a fluorescent tube type LED device in which an aluminum radiator tube and a polycarbonate cover are combined, the fall prevention function is made effective by adding to the fluorescent tube type LED device.

  Provide an attachment function that can firmly fix the fluorescent tube LED device that combines the aluminum radiator tube and the polycarbonate cover.

  Compared with the conventional straight tube type fluorescent tube, the fluorescent tube type LED device is expensive in price.

  If the lighting electronic circuit is built in the aluminum heat radiation tube of the fluorescent tube LED device, it must be safe from electrical leakage. Reduce electromagnetic interference.

  This will be described below with reference to the drawings.

  As shown in the structural drawing of FIG. 2, the fluorescent tube type LED device 2 is a type in which an electronic circuit for lighting an LED element 23 is built in an aluminum heat radiating cylinder 22, and as shown in a cross section thereof, aluminum. The pneum radiator 22 is provided with radiating fin grooves 24a, 24b, 24c.

  As shown in the structural drawing of FIG. 2, the fluorescent tube LED device 2 has a structure in which the fall prevention device 1 is fitted into the fin grooves 24 a, 24 b, 24 c of the aluminum heat radiating cylinder 22.

  FIG. 1 shows a case where a fluorescent tube LED device 2 is attached to a straight tube fluorescent lamp luminaire 3. The fall prevention device 1 can slide and move to a free position.

  When the straight tube type fluorescent tube is removed from the conventional straight tube type fluorescent lamp lighting device 3 and replaced with the fluorescent tube type LED device 2, as shown in FIG. 7, the straight tube type fluorescent lamp lighting device having a different shape size is used. 3 and the fluorescent tube type LED device 2 may have different distances a, so the fall prevention devices 1 having three different heights (1a, 1b, 1c) shown in FIG. 8 were prepared.

  3 is an overall view of the fall prevention device 1, FIG. 4 is a side view of the fall prevention device 1, FIG. 5 is a top plan view of the fall prevention device 1, and FIG. 6 is a bottom plan view of the fall prevention device 1.

  In the overall view of the fall prevention device 1 of FIG. 3, 11 is a nail for fitting into the heat radiation fin groove of the aluminum radiation tube, 12 is an opening for expanding the fall prevention device 1 by inserting a tool such as a screwdriver when fitting. Is a hole for suspending and mounting, and the portion 14 is warped. Therefore, when the mounting bolt 31 is tightened, the claw 11 becomes a fin groove of the aluminum radiator tube 22 of the fluorescent tube type LED device 2. 24a, 24b, and 24c are securely tightened.

  5 and 6 has a shape that can be easily tightened by sliding the fall prevention device 1 without removing the 31 mounting bolts.

  Two bolts 16 for tightening the ground terminal lug are provided at 12 portions of the fall prevention device 1.

    As shown in FIG. 1, since the fluorescent tube LED device 2 can be firmly fixed to the straight tube type fluorescent lamp luminaire 3 by the fall prevention device 1, it is effective even during an earthquake and becomes a complete fall prevention device. At the same time, it is useful as an anti-theft device.

  In FIG. 7, in addition to securely tightening the fluorescent lamp lighting fixture cover mounting screw 31, the ground terminal bolt 16 is used to ground the straight tube type fluorescent lamp lighting fixture 3 with an electric wire, It is also possible to prevent electric shock due to electric leakage and reduce electromagnetic interference.

  As shown in FIGS. 9 and 10, the ceiling T-bar hanging metal fitting 4 and the hanging ring 5 can be combined to be easily suspended directly on the ceiling.

  In addition, the fluorescent tube type LED device 2 has a longer life than the fluorescent tube, and the fall prevention device 1 of the present invention is used in a place where the straight tube type fluorescent lamp lighting fixture 3 is unnecessary, a place where replacement is difficult, or a particularly narrow place. Is valid.

  As shown in FIG. 12, since the lighting circuit is built in the aluminum radiator tube, it is possible to supply power directly from the pin, and without using the straight tube type fluorescent lamp illuminator 3, it is vertically, horizontally and diagonally. It can be mounted securely and freely.

  As the material of the fall prevention device 1 of the present invention, a material having the spring property of stainless steel or steel plate is used.

  When the fluorescent tube type LED device 2 is lit without using the tube type fluorescent lamp lighting device 3, the power may be supplied by the power supply connector shown in FIG.

  Examples of use of the fall prevention device 1 are shown in FIGS.

  nothing special.
